In the present paper, we report the bulk magnetization, electron-spin-resonance spectra and transport properties of Y2Ir2O7. It is found that Y2Ir2O7 exhibits a magnetic transition at Tc=150K and coexistence of antiferromagnetic and ferromagnetic component due to geometrical frustration. The antifer...
